Изобретение относитс к области очистки трубчатой теплообменной аппаратуры и может быть, применено, например, в коксохимической промышленности дл очистки холодильников коксового газа.The invention relates to the field of cleaning tubular heat exchangers and can be applied, for example, in the coking industry for cleaning coke oven gas coolers.
Известны различные средства, примен емые дл этих целей. Напри ер, дл промывки поверхностей нагрева от отложений используют влажный пар путем впрыска LIJ.Various means are known for this purpose. For example, wet steam is used to flush heating surfaces from deposits by injection of LIJ.
Это средство вызывает усиленную коррозию и быстрый выхоц аппаратуры из стро .This tool causes increased corrosion and rapid release of equipment.
Цель изобретени - снижение коррозионного действи реагента на очищаемую аппаратуру.The purpose of the invention is to reduce the corrosive effect of the reagent on the equipment being cleaned.
Эта цель достигаетс примененном лгиохимически очищенных от фенолов и роданидов сточных вод коксохимического производства в качестве средства пл очистки теплообменной аппаратуры от отложений .This goal is achieved by applying the chemical-chemical wastewater-treated phenols and rhodanids from the coke-chemical production as a means of cleaning the heat exchange apparatus from deposits.
Разрутиение отложений происхоцит вследствие жизнеде тельности микробов, Destruction of sediments by the cells due to the viability of microbes,
при которой труанорастворимые в воде фосфаты кальци , железа и магни , содержащиес в накипи, переход т в легкорастворимые соединени . Разрушение накипи вл етс одним из условий активной жизнеде тельности бактерий.wherein the water-soluble calcium, iron, and magnesium phosphates contained in the scale are converted to readily soluble compounds. The destruction of scale is one of the conditions for the active viability of bacteria.
Ускорению разрушени отложений способствует образующа с в результате разложени органических веществ углекислота , котора , соедин сь с карбонатами кальци и магни , переводит их в растворимый бикарбонат.Наиболее интенсивно взаимодействие . обезвреженной сточной воды с накипью происходит при температуре 7О-80 С аэрацией воды,Acceleration of organic matter decomposition is promoted by carbon dioxide produced as a result of the decomposition of organic matter, which, combined with calcium and magnesium carbonates, converts them into soluble bicarbonate. The interaction is most intense. neutralized waste water with a scum occurs at a temperature of 7O-80 With aeration of water,
Использование биохимически очищен-, ных сточных воа коксохимического производствл п{юдотвра1цаег преждевременный выход из стро аппаратуры вслеаствие снижени коррозио1шого действи про..мываюшого юагента.The use of biochemically purified wastewaters of the powder-and-chemical production p {yudotvratsiya premature failure of the equipment due to the reduction of the corrosive effect of the washing agent.
